DEVICE FOR THE EVACUATION OF WASTE SCRAPS FROM KI'ICHENS OR THE LIKE.

Application filed August 2, 1927, Serial No.,210,129, and in Franee'Aug-uste, 1926;

This invention has for its object the provision of evacuating devices for dealing with waste scraps from kitchens by means of a fixture over the sink operated by a flushing of water and the reception of the scraps thus diverted into drainingboxes placed under ground.

With this object each kitchen is provided with a sink-drainer placed under the water tap, whicn is prevented from overflowing by a waste preventing device and the liquid seal ing of which is assured by means of a siphon;

furthermore the sink-drainer is provided at its base with a plug or obturating valve that is operated when the scraps are to be ejected.

The annexed drawings shew, by way of example two methods of carrying the invention into ei'l'ect.

In the drawings Fig. 1 is a longitudinal section of one form of sink-drainer made according to the invcntion.

2 shows an elevation of a special key for operating the obturating valve.

Fig. 3 is a longitudinal section shewing a variation in the sink-drainer.

The sink-drainer shown in Fig. 1 comprises a sink of stone, enamelled cast iron or other suitable material, a, placed under the kitchen tap, which receives the washing water used I for the hands, vegetables, and crockery, etc. and comprising at its central part a removable sieve or plate 6 of aluminium or other suitable material, provided with apertures 0 for the passage of water and its reception in a truncated conical bodyd which supports the sink a. The base of the body (Z is fixed to a cone 6 seated and sealed in the floor.

The upper part of the body (Z of the drainer parts, j, the lower part f of whichis fixed by its edge to the body (Z whilst the upper part or central piece 7 is carried by a three armed support 9, itself fixed tothe body (Z.

In the support 9 and the piece f is disposed, in such a way as to enable it to slide therein, a waste or overflow pipe 7L pierced at its upper part with orifices or openings ]L1 which permit the passage of the water to the interior of the pipe h. This water flows to a double cup-siphon i, the plate of which supports a a plug or obturating valve y' and is perforated with draining holes 2'. The valve or plug 7' which is fixed to the central pipe it includes in is providedwith calibrated covering: in two 7 its interior the cup-siphon z and is furnished on the exterior with an ind'ia rubber ring-7c resting on a fixed seating Z. i

In Fig. 2 is shown a key on with projections permitting the upper plate 6- easily to be raised for its removal, allowing the tube It together with itsjobturating plug to be raised.

Z51 erl/zorl of 0pcmt2'0n.The body (5 of the sink drainer containing a certain quantity of water due to culinary operations, haspassed thereinto according to their production the household scraps which are sent to the d0wntall pipe and from there to the receiving apparatus in the following manner. The cover Z), is raised andthe scraps are thrown on to the calibrated cover. Those which .are of small enough dimensions pass freely through the cover and fall to the bottom, collecting above the plug j, the scraps which are too large, which have been stopped above the disc f are withdrawn and reduced by any desired means to dimensions sufllciently small so that they can pass between the parts 7 and They can then fall to the lower partof the apparatus. To evacuate the scraps accumulated above the plug the key m is introduced into the upper part of the tube h where it catches in one of the holes k and the whole is raised; that is. to say the plug'y' opens or uncovers I lower end or orifice of the body d of the drainer. The scraps which are drawn down by the water in the apparatus fall through t e to the downfall pipe n which opens above a receiving apparatus. I

Fig. 3 shews in vertical section varied form of sink-drainer to that shown inFig. 1.

In this simplified construction the body d is extended into a seating cone (Z for the obturating plug 7'.

The calibrated cover in two pieces 7, and the support 9 of Fig. 1' is replaced by a calibrated cover 7) having holes 0 formed in a single piece f constituted by a plate of special form suspended bythree'arms P which are- The removable key on Fig. 1 is The method of operation ofthe sink drainer as modified is similar to that of the apparatus described with respect to Fig. 1.

Vhat I claim and desire to secure by Letters Patent of the United States of America 1. A device for the evacuation of the waste scraps from kitchen directly by slnk-drainers comprising: a sinkbody with a rim, a. trunable waste pipe guided atits upper part in support for the calibrated covering; openings at the upper part of this pipe, an obturating plug fixed at the base of the waste pipe; a i cm 1c 0 or at tile ex r1 1' )1 1 tghtmlr d asl teoctle plug; a truncated conical seating for the obturated plug; a seated cone placed under the base of the drainer and a (llSCllHl'P'G n )e into a c i whichv opens the seated cones 2.

3. A device for the evacuation of waste scraps from kitchens directly by sink-drainers comprising: a sink body with a rim; a lower truncated conical body supporting the body of the sink and receiving the water coming from this latter, a centralinetallic cover to direct the scraps in the truncated conical body; a movable plate covering the open bottom of the body of the sink; holes for the passage of water in this plate; a central movable waste pipe overiow openings at theupper part of this pipe; an obturating valve fixed to the base of this waste pipe; a tight packing disposed at the exterior of the valve, a seat for the obturating valve formed at the base of the truncated conical body, a seated conduit placed under the base of the drainer; a bowl or cup with a siphon disposed in the interior of the plug and into which dips the base of the waste pipe, and a discharge pipe.

The con'ibination with a kitchen sink having an opening in its bottom, a hollow supportin base registering wit-l1 the opening, a removable drain cover for the opening, a valve closing the lower end: of said base, a valve stem constituting a hollow overflow pipe and means in the valve to water-seal the stem.

5. The combination with a kitchen sink having an opening in its bottom, a hollow truncated body registering wita said opening beneath the sink, a drain cover for the opening, means in said body below the sink to permit the passage of larger particles of" kitchen waste into said body after removing the cover, a hollow valve at the lower end of said body,
